I have a post and rafter barn with 3x interior centerline

Customer Question

I have a post and rafter barn with 3x interior centerline posts approximate 10' on center and 10' from each side wall. I would like to install beams across the approx. 24' span, tie the vertical posts into the new beams, and then cut/remove the posts below the new beams to give a free span area of approx. 24' x 40'. I am trying to determine the size and qty of beams required to support the overhead load. The new beams would sit on the top plate of the side walls so they probably cannot be large than 10".

Can you post a sketch for me? The description is not clear enough to give me a good mental image.

But not for a few hours.

No problem! Thank you!

Here are some photos and a plan view sketch to help. It turns out I really only need to span across the barn in two locations. You'll see the vertical posts on either side of the Seahawks flag. There is an interior wall between the 2nd post and an exterior wall I will remove once the post is cut. This will give me about 24' x 30' free span. I have also included a photo of the side wall posts and framing on top of which I believe any cross-beams would sit. The cross beams would be installed perpendicular to the ridge beams. At least, that's what I am thinking.

Have you had a chance to look at the images and sketch I uploaded?
Expert:  StructuralEng replied 1 year ago.

Yes. Thank you for the sketches. I understand the framing now. What is the city and state so I can look at snow loading? This is to support the roof only, correct?

Yes, this just needs to support the roof load.

Also, if it matters, we sit at 6600' elevation.

Hi. Wondering if you are still planning to give this attention. Thank you.
